This beautifully conceived album offers a snapshot of music in one of the most exciting cities in the world during 1900—Vienna. The art form’s language was changing, and listening to these five different composers here is to experience the direction in which music was headed. The melodic richness of the wunderkind Korngold’s Piano Trio, Op. 1 moves effortlessly to Zemlinsky’s Clarinet Trio and to a pair of Mahler song transcriptions before tonality starts to melt in Berg’s Piano Sonata and clarinet pieces. The collection closes with Schoenberg’s intricate, mesmerising Chamber Symphony. Faultless performances.
